Which term corresponds to verifying the identity of the user or device attempting to access the system?

• A. Integrity
• B. Authentication
• C. Confidentiality
• D. Availability

Answer: (B)

Authentication is the process of verifying the identity of the user or device attempting to access the system. It answers the question: is this really who I think it is? Once identity is confirmed, the system can then apply access controls to determine what that entity is allowed to do. This is different from integrity (keeping data unaltered), confidentiality (preventing unauthorized access to information), and availability (ensuring the system and data are reachable when needed). Common authentication methods include passwords, tokens, biometrics, and multi-factor approaches.
